update xtreme 5.3 to ixtrme 1.2 ms25 drive VIA VT6421

I need some adive, I dont know what I am doing. I had my ms25 samsung dvd drive flashed/modded with xtreme 5.3 a few months ago. now I can do it myself, I have a VIA VT6421 SATA PCI Card with 3 ports and one IDE. I want to flash the ixtreme 1.2 firmware. I think I have it set up right.
I grounded the xbox, i pluged the SATA cable in the #1 Port on the card
I have a iprep boot disc with the ixtreme firmware.

Now I turn both on, boot into dos, and type "mtkflash r /m orig.bin"
because the system was modded, there is no orig.bin there anymore

I dont know what I should do, is there someone with a file that will work on a ms25?
Am I able to use samtool and extract from the hacked.bin(gusing thats whats there) and flash the ixtreme?
Dont know how to get the 12 digit serial from the hacked firmware

Plus when I type the mtkflash line(s) in DOS, My VIA chipset is now showing up, all i get is 2 IDE choices, one primary, one slave...or somthing liek that.

are there special drivers I can download? can anyone give me the how to?

easiest way is to use xtreme boot maker as i said in your other post, which you should still be using, and make sure your using your sata card as your custom mtkflash thing. if you do that right you can just take your hacked firmware that you already have on there and use the x360 command to copy the key into your new firmware then flash the drive and be done.

I cant get my VIA VT6421 to show while using MTKFlash from DOS all I get is 2 IDE primary and slave secondary drives.

So I edited MTKFlash, and now I need ot know WHERE I find the option to turn RAID off.
I cannot update my drivers or roll them back, the driver I installed (1st timer) is the newest driver for the chipset.

command I use is instead of orig.bin I used hacked, but doesnt make any difference because my SATA isnt showing uup in the drive choice menue.
PLEASE someone help.
